10 Claims.

'This invention 'relates to separable fasteners employing stringersadapted to becoupled and uncoupled by a slider movable along thestringers. More particularly, the invention relates to .a detachable endstop coupling for one end portion of the stringers, by means of whichthe stringers may be coupled and uncoupled when the slider is arrangedadjacent said end stop and further, whereby the end stop coupling may beforcibly separated to detach and uncouple the stringers at said endportion for the purpose of freeing or opening predetermined portions ofa garment such, for example, as the upper or lower part of a shirt,sweater, jacket, ,windbreaken or like garment. The novel features oftheinvention will be best understood from the following description whentaken together with the accompanying drawing, in which certainembodiments of the invention are disclosed, and in which .theseparateparts are designated by suitable reference characters in each of theviews; and in which:

Fig 1 is a plan view of one end portion of a fastener made according tothe invention showing the stringers coupled together with one of ourimproved end stop couplings.

Fig. 2 is a view similar to Fig. Y1 showing the parts in detachedrelationship preparatory to coupling engagement.

Fig. 3 is a section on the line 3 3 of Fig. 1. r

Fig. 4 is a perspective view of the .end portion of one Stringer; and

Fig. 5 is a diagrammatic view illustrating the forcible separation ofthe coupled end of the stringers with the links of the other endAportion of the Stringer in engagement with each other.

In fasteners of .the kind under consideration applied to sweaters,jackets and similar garments where complete separation of the fastenerstringers or chains is desirable, couplings have been provided at oneend. of the stringers or chains for similar garment when the wearer isin seated pcsition, or to give access to pocketsin under garments. suchas vests, trousers and the like,with out completely opening4 the jacket,sweater or other garment; In other uses, it will provide sep--l arationvof the upper neck portions of the garment. To render such fastenerdevices practical,

links or scoops of the double acting or reversible `or scoops I6. As thelinks or scoops applied to `both stringers are of identicalconstruction, the

complete separation thereof, the couplings also serving as an end stoplimiting movement of the slider in one direction on the stringers. Indevices of this kind as applied to jackets and similar garments, it hasbeen impossible to separate the stringers at the end portion having thedetach'-, able couplings without completely separating the fastener. 4

It is the purpose of our invention to provide a detachable coupling andend stop for stringers which can be forcibly detached so as to separateand spread the coupled stringers at said end porof the stringer I I iswhat is commonly termed the tion thereof, while leaving the otherendportion of the stringers in coupled relationship.- This provides openingof the lower portion of a jacket or the Stringer.

23 longitudinally with respect to the' box brief description of one willapply to all. Each link or scoop comprises a yoke shaped mounting end I1arranged upon the beaded edges I4, I5 and a substantially diamond-shapedcoupling end I8 which forms upwardly and downwardly directed triangularcouplings I9 adapted to engage V- shaped recesses 20 inthe links ofopposed string ers. Each recess 20 has centrally thereof a couplingelement 2| adapted to enter a channel 22 in the outer surface of thelinks of an opposed Stringer, note Fig. 4. 4

By employing links of the type disclosed, it will be 'apparent that thestringers may be coupled and uncoupled in a universal manner and bysliders moving in either direction on the stringers regardless vof thearrangement of the sliders o n.

Secured to the bead I4 of the strlnger III,y adjacent, ,but spaced fromone end link I6, is a pin part 23 of a detachable coupling. The width of.this pin part across the tape is slightly less than the correspondingwidth of the the'v recess 20 of the end'link of the Stringer I I, the

nose being forked to receive the coupling 2|. in-

said recess. l

Arranged longitudinally of the beaded edge, I-B

box part 26 of the coupling. This part, inthe construction shown,comprises an elongated pin portion 21 substantially similar-to theppinpart '20, .excepting that the rib 24 is-not included'and the outer endof the pin 21 has an inturned stop flange 28 which checks movement ofthe pin part Dart 26. Arranged on opposed sides ofthe pin portion 21,adjacent the flange 2l, are 'similar spring plates 29, outer edges ofwhich are curved inwardly and then outwardly to form elongated clipflanges Sli. The flanges Il are adapted to engage the edges 3i of thepin part 23, as is clearly illustrated in Fig. 3 of the drawing.yHowever, by exerting a pull on the stringer Il, the pin part 23 may beforcibly withdrawn from the box pari, 2B to separate the correspondingend portions of the stringers I and I i in the manner illustrated inFig. 5 of the drawing, while leaving the links i6 coupled at the otherend portions of the stringers.

In the construction shown, the spring clips are formed on the plates 29which are riveted o1' otherwise secured to the pin portions 21, asindicated at 32, the rivets being preferably formed integrally with thepin portion 21 and will extend through apertures formed in the plates 29and then being riveted over in the assemblage of the parts.

In the normal use of the fastener stringers, and when the stringers areseparated in the manner indicate in Fig. 2 of the drawing, the sliderSlis arranged upon the box part 26 with the narrow end portion 34 of theslider abutting the lower edge 35 of the plates 29. The pin part 23 isrst passed laterally through the open side of the slider 33 and then ismoved upwardly into the box part 26 between the plates 2! until the endof the pin part strikes the stop flange 28. With the parts thusassembled, the slider may then be' moved along the stringers to couplethe links thereof.

of the clips l0 may be engaged by a finger 'of the hand to flex itoutwardly to assist in this operation, this latter procedure beingdesirable with the larger types of separable fasteners. that is to say,where the links are of large sizes, commonly referred to in the trade asNo. Tand No. sizes.

With a fastener of the type and kind under consideration, it will beapparent that in addition to providing for the opening of a lower por-Vt'on of a jacket as described, the neck portion of the Jacket may alsobe partially opened, while,

at the same time, maintaining the jacket in coupled relationshipintermediate the stringer ends.'

Fasteners of this type and kind will iind other practical uses invarious installations, generally where it is desirable to obtain quickaccess to both end portions of an article controlled by the fastener. Itmight be said that the pin and box part l structure of the fasteneroperates in the manner of a snap coupling where the parts may beforcibly detached against the action of a spring retaining means andrecoupled by snapping the pin partinto'the socket orboxpart. Y It willalso be understoodthat instead of arranging the detachable coupling at.the lower portion of a garment, as for example in jackets in the mannerheretofore described, that the detachable coupling may be disposed atthe top neck portion of the garment and forcibly separated to control aneck opening. In such installations. the slider may be moved along thelower ends of It will be understood that the `flanged side walls 36 ofthe slider are so spaced apart as to clear the pin 23 and the stringersin controlling the separation or spreading of the lower portion of thegarment.
